Title: Flow meter diagnostics
Inventor: HAIRSTON RONALD JAMES
IPC: G01F25/00
Filed: 2007-02-14
Granted: 2016-01-12
Abstract: Apparatus and associated systems, methods and computer program products relate to monitoring the performance of an operating gas meter by automatic and substantially continuous differential pressure (dP) measurement. Measured dP may be compared against a baseline dP characteristic to determine if the measured dP exceeds a threshold value above a baseline dP characteristic. If the threshold is exceeded, then the system may generate a signal to request repair or replacement of the meter. After installation, some embodiments collect dP data over time and/or over a range of flow rates to automatically learn a baseline dP characteristic under installation conditions. A system may switch from a default baseline dP characteristic to a learned baseline dP characteristic. Some embodiments may further correct volume or flow rate signals for line pressure and/or temperature. Further embodiments provide a passive apparatus to protect a dP sensor against transients in line pressure and/or differential pressure.

Abstract: The invention relates to real-time scheduling management such as wireless, mobile, real-time workflow and scheduling for homebuilding. Mobile devices are assigned to users associated with projects and lots. The mobile devices provide access to project and lot information. Each mobile device is capable of operating independently without a continuous connection to a central system. Performance of production tasks is tracked for each project via real-time monitoring by the users. Task performance data is reported to a central ERP system where real-time performance of the production tasks is compared to scheduled timetables for the production tasks. Scheduled tirnetables for production tasks is modified and updated based on performance data for the production tasks and additional real-time input from the individuals. Compensation is coordinated with the performance data, including enabling payment for completed tasks from the mobile devices via purchase orders. Updates are synchronized between the mobile devices and the ERP system.

Title: Method and system for maintaining consistency of a cache memory by multiple independent processes
Inventor: ROS FREDERICK
IPC: G06F12/0806
Filed: 2006-03-08
Granted: 2014-08-19
Abstract: The invention concerns a method and a system for maintaining consistency of a cache memory, accessible by multiple independent processes. The processes can share common data. The processes perform simultaneous data searching operations optionally followed by providing the data to the processes, a removal of same or an insertion of new data. The searching, removal and insertion operations, are comprehensively executed once they have been initiated by the independent processes. They are executed excluding one another when they must operate on common data. The removal or insertion operations are each completely reversible. In that context, the invention provides that the operations for providing, removing or inserting the data have a finite or bound duration of execution so as to prevent any locking. In particular, the insertion operation, which includes a step of releasing an input when a partition of the cache memory is full, if it requires browsing through the entire partition to make a selection, is however possibly interrupted if the maximum browsing time is reached. In that case, the most appropriate input, among the already browsed inputs, is released. The inputs of said partition are browsed exhaustively, which results from storing the last consulted address of the partition after each release.
